Pocket Lidar for Trench Measurement

Publication Information

Publication Type:
Technical Note
Publication Number:
FHWA-HRT-25-015
Abstract:

For this technote, the research team collaborated with the Pennsylvania Department of Transportation (PennDOT) to perform the following tasks:

  • Assess the ability of pocket lidar (PL) to perform 3D reconstruction of a trench and the accuracy of that 3D reconstruction.
  • Evaluate the accuracy of derivative metrics extracted from the PL point cloud data, such as volume or pipe dimensions.
  • Analyze and discuss the opportunities and challenges of using PL to measure trenches and utility lines.
